C8051F393-A-GM

Overview

The C8051F393-A-GM is an 8-bit mixed-signal microcontroller from the C8051F39x family, featuring a pipelined 8051 core with up to 50 MIPS throughput at a 50 MHz clock. It integrates 16 kB of in-system programmable Flash memory and 1 kB of internal data RAM (256 bytes + 768 XRAM). The device operates on a supply voltage of 1.8 V to 3.6 V and supports an extended temperature range of –40 °C to +105 °C. It is housed in a compact 20-pin QFN package.

Feature Summary

• High-performance 8051 core with pipelined architecture for efficient instruction execution
• Integrated analog peripherals including a 10-bit ADC and dual 10-bit current output DACs
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible clocking system with precision internal oscillators and support for on-the-fly source switching

Applications

• Battery-powered systems requiring low-power stop mode operation
• Industrial control applications utilizing multiple serial communication interfaces
• Motor control implementations leveraging PWM functionality
• Sensor interface designs using integrated analog-to-digital conversion

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS standards as indicated in official documentation. Check for any relevant product change notices affecting manufacturing origin or assembly location prior to procurement.

Selection Notes

Select this model when a small form factor MCU with integrated analog capabilities is required. The C8051F393-A-GM offers code and footprint compatibility with the C8051F33x series while providing enhanced performance and extended temperature ranges. Consider the available I/O count and peripheral set against application requirements before finalizing the selection.

Part Context

This component belongs to the C8051F39x/37x family of mixed-signal MCUs, representing a next-generation evolution of the C8051F33x series. These devices are designed as standalone system-on-a-chip solutions, integrating essential power management features like voltage monitors and watchdog timers directly onto the silicon die.

Replacement Considerations

The C8051F392-A-GM serves as a direct pin-compatible alternative within the same family, differing primarily in the absence of certain analog peripherals found in the F393 variant.
